Daliang, who has not studied the magic array too deeply, cannot see the function of this cave in the entire magic array system.

However, since the magic circle has been destroyed and stopped operating, even if there is danger in this cave, it is limited.

I guess so……

Anyway, Daliang will never allow such a big hidden danger to exist near the fortress.

Whether it is to obtain sulfur ore or to resolve possible crises inside, you must first enter it.

"Astro, Roar, Hurricane, you three are guarding the entrance of the cave. No matter what comes out of the cave, you must kill them as soon as possible. In the Kingdom of Death, we have no allies. Monica is responsible for the construction and defense of the fortress. Julian and I go inside to check."

The heroes replied, "Yes, Lord Lord!"

Monica was in charge of the fortress, and three frost dragons stood around the entrance of the cave.

Seeing that everything was arranged, Daliang called out three demon spirits and threw a ball of light into the hole.

No monsters were seen.

At Daliang's instructions, Julian called out a light shield and walked into the cave first.

The white light emitted by the light shield illuminates the road ahead.

Dry, hollow.

There was no danger, Daliang followed him in.

The scent of sulfur is even more pungent.

There are obvious signs of manual digging in the entire cave passage. The ground at the foot is very solid and flat. You can see that some raised rocks have been cut off from the pavement.

The passage has also been expanded and reinforced, and it is like walking in a tunnel through mountains. The road surface is flat and the walls are solid, as if it is to allow large creatures to pass quickly.

Think about the undead bear and skeleton mammoth you saw during the battle.

Can larger creatures be summoned here? It is just that the teleportation array destroys the integrity of the entire magic array, which makes it not work?

Looking at the size of this passage, Daliang was a little suspicious that this was prepared for summoning the dragon.

The teleportation array landed in the bone burial place and happened to be stuck on a magic node. Daliang didn't know whether he was unlucky or lucky.

Remind Julian that there might be a dead dragon here, and the two of them were more careful.

The passage kept going downward, but Daliang's imagined attack did not appear.

The hole behind is no longer visible, and the unique fluorescent mosses of the underground gradually appear and increase, providing light enough for the dark underground environment to see things.

[Ding, you occupy a sulfur mine: rich mine, with a maximum daily sulfur yield of 2.5 units, 0/50 for labor.]

A system prompt suddenly appeared in Daliang's prompt bar, and after turning a corner, Daliang saw the mine he was looking for.

In front is a large underground cave, with golden sulfur veins on the walls.

Like golden pythons, winding and hovering in the hole.

Magic arrays are embedded on these sulfur ore veins.

The ability to successfully occupy the sulfur mine means there are no monsters here that guard the mines.

And the role of this sulfur ore is already obvious.

This is not prepared to summon some super-large undead creature. The magic arrays embedded in the sulfur mineral veins are used to directly convert the sulfur here into magic power, providing energy for the summoning array in the entire bone burial land.

The guy who built this magic circle is so talented.

Daliang was also glad that he destroyed the summoning array in time, otherwise he would have fought with this sulfur-rich ore to consume.

Even if I sell all my money, I can't fight for a mine.

In this way, this cave is to provide energy for the magic circle. If there is no monster, you can be mined with confidence and boldness.

Just as Daliang was about to return to the fortress to arrange personnel to come in to dig sulfur, Julian pointed to the other side of the cave and said, "Sir, there is still a hole there. For safety reasons, let's go over and check it."

Following the direction Julian pointed, Daliang also saw a circular hole, the same size as the hole that came in, and was seventeen or eighteen meters wide.

It was obviously also excavated.

The Wizard Guild will not dig such a large passage for no reason, and there must be other things deep in the passage.

The defense of the fortress cannot tolerate any sloppyness.

Julian and Daliang walked through the sulfur mine cave and walked into the newly discovered large hole.

And they didn't go too far, they saw a large portal standing in front of them.

【One-way Portal】

A special existence of the teleportation array, such a portal can only pass through one direction.

This portal, standing in front of the bright eyes, filled the entire passage, with silver light emitting like a mirror that could not reflect the image, and circles of ripples popped out of the mirror from time to time.

This side should be the passable side of the one-way portal. If you pass it here, you can reach the other side of the portal, but you cannot return.

What was the Wizards Guild trying to build such a large one-way portal in this place?

You should know that one-way portals are much more complicated than two-way portals. Such a one-way portal with a diameter of more than ten meters is absolutely no less than the super-large summoning magic array in the bone burial land, and the energy consumption of blocking the entry of the other side is also very huge.

Daliang suspected that the sulfur mine itself was the same super rich mine as his crystal mine on Feichen Island. As a result, in order to maintain the operation of this one-way portal, it was cut to two units of sulfur-rich mines in Nissan.

This is the output of the summoning array without running. If the summoning array is estimated to be not destroyed, the output here should be infinitely close to 0.

A project that needs to be at the cost of super rich mines is really an unimaginable big deal.

I guess when the Wizard Guild knows the current situation here, I will definitely tear my heart.

As for the role of the entire project, Daliang has basically guessed it.

When the Wizard Guild needs it, this large summoning magic array covering the entire bone burial land will continue to summon a large number of large-scale advanced undead spirits.

Then they should have a way to get these advanced undead to gather in the center of the magic circle, and then follow the passage through the sulfur mine and rush out from this one-way portal.

This channel that was chiseled out and expanded in a flat manner can allow the undead to pass quickly.

You can imagine what the other side of the one-way teleportation array will be once it is activated here.

Have you seen a flood discharge from dams?

The tide of advanced undead can sweep everything, and the person on the other side can only cut off these undeads from the source if they want to stop them.

The entire summoned magic circle is in the burial place where the opposite creature does not know its location.

And when they rushed here against the undead tide, they would find that they were facing a one-way teleportation array, a one-way teleportation array with a super rich mine power supply. It is definitely not an easy task to destroy it.

If the Wizard Guild activates this place, it will be a catastrophe for the people opposite the one-way teleportation array.

The undead natural disaster!
